Power Consumption
The power consumed by the XC2735X depends on several factors such as supply
voltage, operating frequency, active circuits, and operating temperature. The power
consumption specified here consists of two components:
The switching current
I
S depends on the device activity
The leakage current
I
LK depends on the device temperature
To determine the actual power consumption, always both components, switching current
I
S (Table 16) and leakage current ILK (Table 17) must be added:
I
DDP = IS + ILK.
Note: The power consumption values are not subject to production test. They are
verified by design/characterization.
To determine the total power consumption for dimensioning the external power
supply, also the pad driver currents must be considered.
The given power consumption parameters and their values refer to specific operating
conditions:
Active mode:
Regular operation, i.e. peripherals are active, code execution out of Flash.
Stopover mode:
Crystal oscillator and PLL stopped, Flash switched off, clock in domain DMP_1
stopped.
Note: The maximum values cover the complete specified operating range of all
manufactured devices.
The typical values refer to average devices under typical conditions, such as
nominal supply voltage, room temperature, application-oriented activity.
After a power reset, the decoupling capacitors for
V
DDI are charged with the
maximum possible current.
For additional information, please refer to Section 5.2, Thermal Considerations.
Note: Operating Conditions apply.
